one is watching all the readings together which "make sense". If one reading is out from where it should be relative to the others (for the given load/condition) it is investigated immediately so anomalies don't usually go unnoticed. One gets a sense.. a feeling for the whole.. like a simulation running in your own head to feel whats going on as well.
